<![CDATA[Nationalism and national identity are dynamic social constructs that continuously evolve in response to technological advancements and the emergence of the post-truth era. The rapid growth of digital media has transformed the public sphere, enabling the widespread dissemination of information while simultaneously increasing the risks of misinformation, disinformation, identity polarization, and echo chambers. This study aims to analyze the theoretical concepts of nationalism and national identity in the digital and post-truth era, identify the major challenges faced by nationalism in cyberspace, and formulate strategies to strengthen critical and character-based nationalism through civic education and digital literacy, and Implications for National Identity with Character. This research employs a qualitative approach using a literature review method. Data were collected from accredited national and international scientific journals, and related publications published within the last ten years. The data were analyzed through content analysis and thematic analysis to identify, classify, and synthesize the main findings from various sources. The findings indicate that nationalism in the post-truth era faces significant challenges, including the spread of false information, social identity polarization, low levels of digital literacy, and the influence of globalization on local values. The study also reveals that strengthening nationalism requires the integration of civic education, digital literacy, and digital citizenship practices. Furthermore, the internalization of Pancasila values, critical thinking skills, and responsible participation in digital spaces play an essential role in fostering an inclusive and resilient national identity.Collaboration among educational institutions, government agencies, digital platforms, and society is crucial for maintaining social cohesion and strengthening national identity in the digital era.]]>
